Import 115um 120um Brass Coated Ultra Fine Sawing Wire — Buy in wholesale FOB from Supplier in China

This brass coated ultra fine sawing wire, supplied at 115 micrometre and 120 micrometre diameters, is a high-carbon cold-drawn steel wire plated with brass for use in multi-wire saw machines. The brass coating provides lubricity and corrosion resistance during the abrasive slicing of silicon ingots, while the high-carbon steel core delivers the tensile strength needed to maintain wire tension at high cutting speeds. Henan Hengxing PC Steel Product Co., Ltd, part of the publicly listed Henan Hengxing Science & Technology group (stock code 002132), manufactures this wire at scale for the photovoltaic and semiconductor supply chain.

The wire is spooled onto industry-standard H-wheels compatible with common wire saw platforms, including NTC210, BS200, BS64, and BS126 types. Spool lengths are determined by the take-up capacity of the buyer's machinery, and the supplier states it can accommodate custom spool specifications on request. Typical wire properties for this category include a tensile strength in the range of 3,200-3,800 MPa, a brass coating thickness of 0.2-0.5 micrometres, and diameter tolerances held to within plus or minus 1 micrometre to ensure consistent wafer thickness and minimal kerf loss during slicing.

Buyers of this product are primarily silicon wafer manufacturers, solar cell producers, and semiconductor fabrication facilities that require a reliable, high-volume supply of precision cutting wire. The product is also used for slicing quartz and other hard, brittle materials. Pricing, minimum order quantities, and delivery terms are not listed and should be negotiated directly with the supplier. Given the technical sensitivity of wafer slicing, buyers are advised to request wire samples for testing on their specific sawing equipment before committing to bulk orders.
